Title: Fuel feeding device of internal combustion engine
Inventor: FURUHASHI SHIYOUJI
IPC: F02D41/26
Filed: 1979-05-31
Abstract: PURPOSE: To improve driving stability at the time of engine start, by computing fuel to be fed through averaging engine parameters or their operated values of revolution at low gear operation, load, etc.  
     CONSTITUTION: In a block for computing fundamental fuel injection (Tp) from suction air (Q) and engine revolution (N), virtual fundamental fuel injection (Tp') is handled as fundamental one (Tp) without modification when the engine revolution (N) exceeds about 450rpm, but is computed with an exponential averaging expression (Tp)=(2 n -1)Tpo/2 n +Tp'/2 n  using a fundamental fuel injection (Tpo) which is the amount a round (10ms) in advance of the interative calculation. This can keep the fluctuation of fuel feed small during the low gear operation or at the engine start, thus stabilizing the driving performance.

Title: Radar signal-processing apparatus
Inventor: TAKAHASHI KATSUMI
IPC: G01S7/32
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To observe with high accuracy and at the same time shorten a process time by dividing an observation area to a plurality of observation partial areas, and setting different process levels for a plurality of observation partial signals corresponding to the observation partial areas. SOLUTION: A load determination module 35 classifies an observation area to a first, a second areas and the other areas by distances from an observation estimation point, and determines to operate a radar reception signal corresponding to each classified observation area at a predetermined process level. A control module 36 assigns the operation for the radar receipt signals of classified areas to operation modules 30-33. The operation is executed at the process level stepwise higher towards the observation estimation point at the first and second area concentrically divided with a plurality of radii centering the observation estimation point. Although the area where the operation at a higher process level is conducted is narrowed, an object to be tracked can be detected with high accuracy. Moreover, a process load is reduced and a process time is shortened because of the narrowing of the area.

Title: Ultrasonic motor
Inventor: SHIBATA KENICHI
IPC: H02N2/00
Filed: 1989-03-20
Abstract: PURPOSE:To utilize vibration energy of an ultrasonic vibration body efficiently by driving two moving bodies in contact with the opposite faces of the ultrasonic vibration body with traveling wave excited on the opposite faces of the ultrasonic vibration body. CONSTITUTION:When a moving body 7 is driven in the direction L and a moving body 8 is driven in the direction R, central shaft 7' rotates counterclockwise and central shaft 8' rotates clockwise. Consequently, rolling bodies 9, 9, 9, 9 revolves counterclockwise. Assuming any one of the central shafts 7', 8' of the moving bodies 7, 8 is the output shaft to an external device, the rolling bodies 9, 9, 9, 9 transmit the driving force of the moving body 8 or 7 which is not the output shaft to the moving body 7 or 8 having the output shaft so that the moving bodies 7, 8 have same rotation. Since the load on the moving body having the output shaft is also applied onto the moving body which has not the output shaft, load to be applied onto the moving body having the output shaft can be reduced.

Title: Iron-core reactor with cap
Inventor: MISHIMA AKIRA
IPC: H01F27/24
Filed: 1987-03-23
Abstract: PURPOSE:To prevent generation of the compression stress in the central part of a yoke iron core for lowering a noise by forming both end parts in the direction of lamination of the yoke iron cores of a silicon steel band having a large generation loss and the rest central part of a silicon steel band having only a small generation loss in the direction of lamination. CONSTITUTION:Both end parts 4a in the lamination direction of the upper and lower yoke iron cores 4 and 5 are formed of a silicon steel band having relatively many generation losses and the central part 4b in the other lamination direction is formed of the silicon steel band having relatively less generation losses. At the time of operation, a temperature rise due to the generation loss of both end parts in the lamination direction and the central part of the yoke iron core 4 is almost levelled by negating the part due to inequality of a magnetic flux portion through the choice of a kind of the silicon steel band. A batten of each section part of the yoke iron core 4 is evenly extended to prevent generation of excessive compression stress due to a difference of thermal expansion. Thereby, noise can be lowered.

Title: Wafer scribe line structure
Inventor: KITAHARA AKINAO
IPC: H01L21/301
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To make an Al film difficult to peel at a marginal area of a wafer to suppress formation of unwanted broken pieces and improve the production yield in the assembling step of semiconductor chips, by preventing a protective film from being formed on scribe lines. SOLUTION: When integrated circuits 3 are formed after processing various steps, an Al film to form interconnections in the circuits 3 remains on marginal areas of wafers 1. After forming the integrated circuit 3, an insulation material such as silicon nitride or polyimide is laminated to form a protective film 12. To expose pads of the circuit 3 by etching, scribe line parts 20 are also etched to expose the surface of the wafer 1. As a result, the Al film 11 on the wafer 1 is exposed at the scribe lines 20 between the integrated circuit 3 and a marginal area 4. Thus, a part of the Al film 11 is never peeled with the protective film 12 at scribing, and hence the conductive broken pieces will be little produced.

Abstract: PURPOSE:To realize a highly efficient compressed coding, by using a predictive coding and an entropy coding. CONSTITUTION:The output of a TV camera 1 is quantized by a differential device 2 and a quantizer 3 and then converted into the 1st code through the 1st coder 6. This code which received a predictive coding receives a run length coding from a clock buffer memory 7 through the 2nd coder 8.

The picture elements in the memory 11 are read successively and converted into a quantized value through a decoder 12. Then a reproduced picture is obtained through an adder 13 and a predicting device 14 to be displayed or recorded at an output device 15. As a result, a highly efficient coding is made possible with a high compressibility.

Abstract: PURPOSE:To improve the reading speed of an original by implementing binary error spread processing attended with binarization processing of picture data read from the original at a high speed. CONSTITUTION:Multi-value picture data inputted to a binarization processing circuit pass through a delay circuit, an adder circuit and a line memory 21 till the data reach a binarization comparator 23. Then the multi-value picture data on a line 19 to which a binarization error of surrounding picture elements is added are compared with a threshold level fed from a threshold level supply device 22 and converted into binary picture data. Then a subtractor 26 calculates a binarization error of the multi-value picture data for a black reference level from a black reference level supply device 24 in parallel with the binarization processing of the multi-value picture data. Then an output from the comparator 23 becomes binary picture data. On the other hand, a binarization error as to a noted picture element selected by a selector 28 is shared by an error distribution device 29. Thus, high speed error spread processing is executed.
